This worked fine until today and now when I try to tag sources via either amazon.com or amazon.de I get the following error returned:
Error connecting to server: http://webservices.amazon.de
400: Bad Request
As far as I know nothing has changed on the PC. I have tried turning off anti-virus and Windows firewall.
Yes, this could be exactly the problem: that also the date has not changed.
See this thread: /t/11901/1
No, checked the date and it is correct at 04/04/2017
However, the time was out by an hour!
Fixed now. Thanks
